What's Wrong?

Very clear performance degradation of fable 5, not respecting safeguards, not following instructions, losing track of details in the conversation.

I'm done anthropic. So tired of you treating your users like this and trying to cover it up. The lack of transparency - the dishonesty - is unacceptable.

What Should Happen?

DON'T QUANTIZE YOUR MODELS!
